I'm about to buy a new outboard and wanted some opinions on how many horsepower to buy. I have a 1648 Xpress flatbottom and typically fish wish two other guys. We all way a little over 200 pounds. We fish mainly lakes but get in a few smaller rivers. I just want to make sure I have something that's strong enough to push us around 25-30mps.. I was leaning towards a 30hp but wanted opinion. Would a 25hp work? Thanks.
